Inputs
Name | Type | Description |
|---|---|---|
ipSrcImage | Source image (USINT or REAL elements, 1 channel) | |
ipDestImage | Reference To ITcVnImage | Destination image. If ipSrcImage is of type USINT and the reduction type is SUM or AVG, ipDestImage will be of type REAL; otherwise, it retains the same type as ipSrcImage (An appropriate single channel destination image will be created if required.) |
nDim | DINT | Index along which the ITcVnImage is reduced: 0 reduces the matrix to a single row, 1 reduces it to a single column, and 2 reduces to a single channel |
eReduceType | Reduction operation | |
hrPrev | HRESULT indicating the result of previous operations (If SUCCEEDED(hrPrev) equals false, no operation is executed.) |
